Poor man's Force Sensitive Resistor (FSR)

This post is not about making your own FSR from Conductive foam, but how you can get many FSRs from single large FSR. I bet you have guessed...

 You can cut a 60cm FSR into many smaller FSRs that will be still of original sensing quality but much cheaper compared to if you have bought many small factory made FSRs. Consider the cost saving when you get FSR for $20 and cut it into 20 pieces! That's what I've done for one of my projects. Below is a demo comparison of original FSR and cut version:

By the way for good intro to FSRs read following very detailed post
